Absent Period

Relevant specialty: Gynaecology

When menstruation fails to occur, there are many possible reasons – from pregnancy to hormonal fluctuations, stress, or lifestyle changes. An occasionally irregular cycle is common and usually harmless. If your period remains absent for a longer time or this occurs repeatedly, a gynecological examination can help determine the cause.

Possible causes

01

Pregnancy

The most common cause in women of childbearing age. A pregnancy test provides initial clarity here.

02

Hormonal Fluctuations

Stress, travel, significant weight changes, or intensive exercise can temporarily disrupt your cycle. It usually regulates itself again.

03

Transitional Phases

During puberty and in the years before menopause, the cycle is often irregular. This is a natural part of hormonal changes.

04

Cycle or Hormonal Disorders

For example, polycystic ovary syndrome or thyroid changes can affect the cycle. These can be readily examined.

Typical steps at the doctor's office

  1. 1During the consultation, your cycle length, last menstruation, possible pregnancy, and life circumstances will be discussed.
  2. 2A gynecological examination with ultrasound evaluates the uterus and ovaries; if necessary, hormone levels in the blood will be measured.
  3. 3Depending on the results, further steps or accompanying counseling will be discussed.

What you can do yourself

  • Keeping a cycle diary with notes on bleeding and accompanying symptoms makes it easier to assess the situation.
  • As a first step, take a pregnancy test — regardless of whether a pregnancy seems likely.
  • Pay attention to a balanced diet, sufficient sleep, and healthy stress management.
  • Approach significant weight changes and very intensive training with moderation.
When a doctor's visit makes sense

A gynecological examination is advisable if your period remains absent for a longer time without an apparent reason, is repeatedly irregular, or is accompanied by other symptoms. An appointment can also provide clarity if you wish to conceive or feel uncertain.

Frequently asked questions

When is a period considered absent?
If bleeding is absent for three months or three cycles in someone with a previously regular cycle, this is referred to as an absent period (amenorrhoea). A one-off delay of a few days to weeks is common. For women of childbearing age, the first step is always a pregnancy test.
Can stress delay my period?
Yes, stress and significant strain can temporarily affect your cycle. It usually normalizes once the situation calms down.
Should I see a doctor sooner if I wish to conceive?
If you have an unfulfilled wish to conceive and an irregular cycle, early gynecological counseling is helpful to assess the situation together.
